Crawl under the back of the car. See what kind of fuel lines he has and what kind of pump. That will tell you right there what kind of shot he will be running. As for what motor is in it. It doesn't really matter in those cars. They are only fast when they run large amounts of nitrous. If he has a good shot on it, he'll have -8 or -10 lines with a -6 return. Otherwise, you shouldn't have an issue with him.
